Huh. That's weird! No idea what's up with that. If you'd like to go back through the intro/tutorial bit again, open up the game's files (should be in local appdata, look for "Transmute Deluxe"), go into the Options.ini file (you can open it up with notepad or a text editor), and look for the Respawn option. Then, set the x value to 1408, and the y value to 384. If you save that, and then reopen the game, you should start back at the very beginning (but with no forms lost) so you can re-open the puzzles as necessary. Hope this helps a bit!
